Power
Convert kilocalorie per hour (kcal/h) to mechanical horsepower (hp). Power is energy per unit time — the rating of pumps, compressors, motors, and heat duties.
1 kcal/h = 0.001559609 hp
To convert kilocalorie per hour to mechanical horsepower, multiply the kcal/h value by 0.001559609. To go the other way, divide by 0.001559609 (or multiply by 641.1865).
| kcal/h | hp |
|---|---|
| 1 | 0.001559609 |
| 2 | 0.003119217 |
| 5 | 0.007798043 |
| 10 | 0.01559609 |
| 25 | 0.03899022 |
| 50 | 0.07798043 |
| 100 | 0.1559609 |
| 250 | 0.3899022 |
| 500 | 0.7798043 |
| 1000 | 1.559609 |
Rotating-equipment duties are quoted in kW or hp; heat duties in kW, MW, or BTU/hr.
Electrical input, shaft power, and hydraulic power differ by the efficiencies between them — label which one a number refers to.
Worked example. A power of 85984.52 kcal/h is 134.1022 hp.
Multiply the value in kcal/h by 0.001559609 to get hp. For example, 10 kcal/h = 0.01559609 hp.
1 kcal/h equals 0.001559609 hp.
Rotating-equipment duties are quoted in kW or hp; heat duties in kW, MW, or BTU/hr.
